Networking in uncoordinated frequency hopping piconets
First Claim
1. A method of establishing an anchor piconet in a frequency hopping communications system, the method comprising:
- identifying a plurality of wireless units within range of one another;
selecting an anchor unit from the plurality of wireless units;
broadcasting a beacon signal from the anchor unit; and
parking remaining wireless units onto the beacon signal, whereby the anchor unit and the remaining wireless units together form an anchor piconet and wherein the anchor unit relays information that allows the remaining wireless units to create and release independent networks.

Abstract
Networking in uncoordinated frequency hopping piconets includes forming an anchor piconet from a plurality of wireless units that are in range of one another. An anchor unit is selected from the plurality of wireless units. A beacon signal is generated from the anchor unit and the remaining wireless units are locked onto the beacon signal. An additional embodiment the invention in peer-to-peer ad-hoc networking includes establishing at least one anchor piconet and establishing at least one traffic piconet between at least two wireless units in the anchor piconet. The traffic piconet is established using information relayed from the anchor unit to each wireless unit that participates in the traffic piconet. Since the anchor unit knows routing and identification information of all the wireless units, the traffic piconets can be established with minimal delay.

15. A method of peer-to-peer ad-hoc networking in a frequency hopping communications system, the method comprising:
-
establishing at least one anchor piconet, wherein the method for establishing each anchor piconet comprises;
identifying a plurality of wireless units within range of one another;
selecting an anchor unit from the plurality of wireless units;
broadcasting a beacon signal from the anchor unit; and
parking remaining wireless units onto the beacon signal, whereby the anchor unit and the remaining wireless units together form an anchor piconet; and
establishing at least one traffic piconet between at least two wireless units in the at least one anchor piconet using information relayed from the at least one anchor unit to each wireless unit that participates in the traffic piconet.

34. A frequency hopping communications system of peer-to-peer ad-hoc networks comprising:
-
a plurality of wireless units each having low power transceivers;
logic that establishes at least one anchor piconet, wherein the logic that establishes each anchor piconet comprises;
logic that identifies the plurality of wireless units within range of one another;
logic that selects an anchor unit from the plurality of wireless units;
logic that broadcasts a beacon signal from the anchor unit; and
logic that parks remaining wireless units onto the beacon signal, whereby the anchor unit and the remaining wireless units together form an anchor piconet; and
logic that establishes at least one traffic piconet between at least two wireless units in the at least one anchor piconet using information relayed from the at least one anchor unit to each wireless unit that participates in the traffic piconet.
